BOTTOM-DUMPING BUCKET.

Specification of Letters Patent.

Patented Mar. 7, 1911.

To all whom it may concern:

Be it known that I, GUs'rAvUs L. STUEBN ER, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Bottom- Dumping Buckets, of which the following is a specification.

This invention relates to bottom dumping buckets and its object is to produce a bucket with either one or two bottom swinging doors, which have connected thereto a main locking device, obtained by linked connec tions between one of the said swinging doors and the operating arms of the bucket.

A second or safety locking device comprises latches which lock the legs of brackets of one of the bottom swinging doors.

A third feature of the invention comprises means to regulate the amount of the open ing of the bottom door or doors, to secure different angles of inclinations for said door or doors when dumping the charges from the bucket. The bottom swinging doors of :the bucket are preferably extended beyond the lower edges of the ends of the body thereof to constitute extensions or feet for the said body, when the bucket is placed on a support. The main locking device is preferably connected up between one of the ends of the body of the bucket and the extended end of one of the swinging doors. The novel feature of the said main locking device consists in the upward force exerted by the extended end of one of the swinging doors, which force tends to maintain one or a. pair of parallel locking links against one or a pair of operating arms. The locking links by being held stationary prevent the swinging door or doors from opening or swinging down. hen the position or positions of the said arm or arms are changed so that the locking links are no longer locked, the said door or doors are dropped. The operating arms and locking links might be attached to the sides of the bucket and still the spirit of the invention contained in the main locking device would be the same.

In the accompanying drawings Figure 1 represents a side view of a bucket exemplifying one form of the invention, Fig. 2 shows a top plan view of Fig. 1, Fig. 3 is a right hand end view of Fig. 1, Fig. 4 is a view similar to Fig. 1 with the movable ele ments in changed positions, Fig. 5 represents a side view of a second form of the invention, Fig. 6 shows a right hand end view of Fig. 5, Fig. 7 represents a bottom plan view of Fig. (3, and Fig. 8 is a view similar to Fig. 5 with the moving elements in changed positions.

Referring particularly to Figs. 1 to 4 the bucket is shown with a body having the sides 20, ends 21, 22, reinforcing band 23 at the upper edge thereof, and reinforcing plates 24 at the lower portions of the said sides 20, with their ends 25 bent over the corners of the said sides and ends. Reinforcing plates 20 are fastened to the lower portions of the ends 21, 22, of the bucket and extend between the said ends 25. A bail 30 is fastened to the sides .20 of the bucketby means of the angle irons 31. Pivots 35 having the collars 36 and pivots 37 having the collars 38 extend from the lower portions of sides of the bucket, the said col lars 36 and 38 hearing on the plates 24.

The pivots 35 support a bottom swinging door which comprises two swinging brackets that each have a vertical. leg 40 and a horizontal leg 41. Each leg 40 carries a reinforcing block 42 to thicken the bearing for its pivot 35. The said legs 40 also carry a pivot 43 and each has its upper end 44- chamfered to easily lock with its latch to be described. An inverted box shaped frame 45 connects the inner accompanying faces of the legs 41, and a door plate 46 is fastened to the frame 45 between said legs 41. The pivots 37 support a bottom swinging door, which comprises two swinging brackets that each have a vertical leg 50 and a horizontal leg 51, the weights of the legs 50 assisting the lowering of their door when it is in a tilted position. Each leg 50 carries a reinforcing block 52 to thicken the bearing for its pivot 37, and each leg 51 carries a pivot 53. An invert-ed box shaped frame 54 con nects the inner accompanying faces of the legs 51, and a door plate 55 is fastened to the frame 54 between the said legs 51. Connecting links 56 on each side of the bucket connect the pivots 43 and 53. The legs 41 and frame 45 extend beyond the lower edge of the end 21, and the legs 51 and frame 54 extend beyond the end 22 to form respectively the extended ends 47 and 57 for the doors of which they form parts. The doors when in their closed positions constitute feet for the bucket. Hinge stop blocks 60 with the horizontal bearing surfaces 61 are secured to the sides 20, in the paths of the legs 40 and carry the pivots 62 on which latter are pivoted the latches 63 for said legs 4-0. An end bearing face 64 on the latch 63 registers with the bearing surface 61 when the latch is thrown up, and a nose formed at the other end of each latch.

On the outer end portion of the frame 4-5 are fastened two pairs of angle brackets 66 that carry the pivots 67. A pair of angle brackets 70 and 71. 7 2, are fastened to the end 21 of the bucket. A pivot 73 is secured in the brackets 70 and a pivot 7-t is secured in the brackets 71, 72. An operating arm 7 5 is pivoted on the pivot 7 and an operating arm 76 is pivoted on the pivot 74:. An operating bar 77 connects the swinging ends of the arms and 76. Pivots 7S and 79 respectively on the arms 75 and 76 carry respectively the upper ends of the locking! links 80, 81, the lower ends of which latter are pivoted on the pivots 67. Bearing plates 82 are secured to the end 21 for the arms 7 and 76. The bracket 72 has formed there with the segmental member 85 with the holes 86. Chains 87 fastened to the end 21 carry the stop pins 88 normally supported in the pin holder 89 fastened to said end 21. One of the stop pins 88 .is inserted into one of the holes 86 in the path of the arm 76 to control the angularity of the doors when open or in their lowered positions. Two stop pins are provided so that the second one can be inserted in one of the holes 86 when the first one is in place, and then the operator by bearing down on the operating bar can detach the first pin and allow the operating arm 76 to bear up against the said second 'pin. The two stop pins may be simultaneously used to bear on opposite sides of an operating arm to lock the doors. Handles 90 are fastened to the ends 21 and 22 for handling the bucket.

In the modification shown in Figs. 5 to 8 the bucket is shown with a body having the sides 100, ends 101, 102 reinforcing band 103 at the upper edge thereof, and the reinforcing plate 104 atthe lower portions of said sides and ends. A bail 105 is fastened to the sides 100 of the bucket, by means of the angle irons 106. Pivots 107 similar to 35 extend from the lower portions of the sides of the bucket. The said pivots 107 support a bottom swinging door which comprises two brackets, that each have a vertical leg 10S and a horizontal leg 109, similar to the legs 40 and 41 respectively. An inverted box shaped frame connects the inner faces of the legs 109 and av door plate 116 is fastened to the frame 115 between said legs 109 and of large enough area to close the bottom of the bucket without any accompanying door. Braces 117 tie the legs 108 with the frame 115, and the door has an extended end 118 beyond the end 101. Hinge stop blocks 120 similar to the stop blocks 60 are secured to the sides 100, in the paths of the legs 108, and have pivoted thereto the latches 121, similar to the latches 63. On the extended end or extension 118 of the door are fastened two pairs of angle brackets 122, similar to 66 and which carry the pivots 123.

A pair of angle brackets 124 and 125, 126 are fastened to the end 101. A pivot 127 is secured in the brackets 12% and a pivot 128 is secured in the brackets 125, 126. An operating arm 129 is pivoted on the pivot 127 and an operating arm 180 is pivoted on the pivot 128, and bearing plates 131 are fastened to the end 101 for said arms. An operating bar 155 connects the arms 129 and 130. Pivots 136 and 137 respectively on the arms 129 and carry respectively the upper ends of the locking links 138, 139 the lower ends of which latter are pivoted on the piv ots 123. The bracket 126 has formed therewith a segmental member 140 similar to 85. Chains 141 with stop pins 142 similar to 88 are fastened to the end 101 of the bucket, and the handles 143 are fastened to the ends of the bucket.

Referring to Figs. 1 to l and to charge the bucket with the material to be handled, the operating arms 75, 76 and locking links 60, 81 are brought to their locked positions which maintain both the swinging doors closed with the body of the bucket. \Vhen the charge is to be dumped the operator raises the operating bar 77, which raises the. operating arms, 7 5, 76, the locking links 80, 81, and swings down the legs a0, lowering thereby the door with which the latter are connected. \Vith the swinging down of the legs 40 the connecting links 56 lower, which causes the other door of the bucket to lower. The lowering of the doors discharges the load from the bucket.

The latches 63 with their arms 10, and the latches 121 with their arms 108 constitute respectively safety looking devices for their respective swinging doors. The moment of force produced by the weight of the door having the legs 40 with respect to the axial center of the pivots 35, transmits force to the pivots 7 S and 79, and forces the said legs 40 against the noses 65 of the latches 63.

It will be noted that when the swinging doors are closed up against the body of the bucket that the axial centers of the pivots 7 8. 79 are nearer the end 21, than the horizontal distance from said end 21 of a line drawn through the axial centers of the pivots 73, 7a and the pivots 67 thereby maintaining the operating arms 7 5 and 76 lowered and adjacent to said end 21. producing a locking device with the said operating arms 75, 76, and the locking links 80, 81, for the swinging bottoms of the bucket. It will be noted that in the locking device just above described, that forces are transmitted K from the pivots 67 through the links 80, 81, to the pivots 78, 79 on the operating arm 75, 76. This force increases with increased weight of the swinging bottoms, and the greater the latter the greater will be the forces tending to maintain the said operating arms 75, 76 in their lowered position, and consequently the eiiiciency of the looking device for the doors increases with the increase of the Weights of the charges in the buckets.

The operations of the modified bucketshown in Figs. 5 to S are similar to the operations of the bucket shown in Figs. 1 to 4.

The safety locking devices formed with the latches 63 and 121 are used when there is danger of the other or main locking devices becoming unlocked, as would result if their operating arms 75, 76, 129, 130 or their operating bars 77, 135 were raised, by coming in contact with some obstruction, or were accidentally raised. They are also useful if the pivots with their connectionsof the main locking devices become worn, and which might prevent the pivots 78, 7 9 and 136, 137 being forced sufliciently close to the bodies of the buckets to lock the members of the main locking devices in locked positions.

The bucket shown in the drawings have ends which are inclined to each other, but they may be parallel and in fact the bucket may be made of any suitable form.
